MODE OF CARRYING OUT THE INVENTION AND CREATION

The mode of carrying out the invention and creation is described in detail with reference to accompanying drawings to more clearly understand the technical features, purpose, and effects of the invention and creation.

FIGS. 1 to 3 show a jigsaw puzzle of the preferred embodiments for this invention and creation, which are comprised of a plurality of jigsaw puzzle blocks 10 formed with cutting jigsaw puzzle board 1. For the said jigsaw puzzle blocks 10, the edges on both sides are arc surfaces, convenient to splicing among the jigsaw puzzle blocks 10 of which edges that are not easy to cause injury, and safe in use.

In order to ensure that the edges on both sides of the jigsaw puzzle blocks 10 are arc surfaces, this invention and creation also relates to a fabrication method of the jigsaw puzzle, as shown in FIGS. 2 and 3. Two groups of tool 2 or the first and second tools are employed to symmetrically be set up on both sides of the jigsaw puzzle board 1. Two groups of tool 2 or the first and second tools move opposedly to press and cut the jigsaw puzzle board 1, forming a plurality of jigsaw puzzle blocks 10. Two groups of tool 2 are respectively pressed toward the jigsaw puzzle board 1. Due to action of pressure of the edge 21 of the tools 2, the cutting edges (i.e. the edges formed on the jigsaw puzzle block 10 through press cutting) is bent inward to form arc surface. Also, the tools 2 respectively perform press cutting from both sides of the jigsaw puzzle board 1 such that the edges on both sides of the jigsaw puzzle blocks 10 have arc surfaces, which is convenient to splicing among jigsaw puzzle blocks 10 of which edges not easily result in injury and being safe in use. In addition, two groups of tool 2 or the first and second tools that opposedly perform press cutting. During press cutting, there shall always be spacing between edges of the first and second tool for two groups of edge 21 during press cutting of the said jigsaw puzzle board. The said spacing is between 0.02 mm and 0.2 mm. During press cutting by the first and second tools, the press cutting layer assembly of the said jigsaw puzzle board is cut and the first portion of the said fracturing layer is cut. The second portion of the said fracturing layer has a thickness between 0.02 mm and 0.2 mm. The edge angle, a, of the first and second tool is linearly related to the angles of the arc surfaces for the lateral edges of the jigsaw puzzle blocks. That is, the larger the edge angle, a, is, the larger the angle of the arc surface for the lateral edge of the jigsaw puzzle block is. Preferably, the angular diameter of the lateral edge for the jigsaw puzzle block is between 1 mm and 3 mm.

Furthermore, in order to make the edges on both sides of the jigsaw puzzle block 10 more round and smooth, both sides of the edge 21 on the tool 2, the body 20 of the tool 2, and portion among them have concave arc surfaces.

In order to avoid wear caused by the edges 21 of the two groups of tool 2 being in contact with each other during press cutting, there shall always be spacing between the edges 21 of two groups of tool during press cutting of the jigsaw puzzle board 1. Furthermore, the edges of the said two groups of tool 2 may perform cutting operation on the corresponding positions of two surfaces of the jigsaw puzzle board. For the middle layer of the jigsaw puzzle board 1, the portion which is not pressed and cut may separate a plurality of jigsaw puzzle blocks 10 through fracturing. In order that this portion is convenient to be fractured, as shown in FIG. 2, the jigsaw puzzle board 1 thicknesswise covers two press cutting layers 11 and the fracturing layer 12 in the middle of two press cutting layers 11. Two groups of tool 2 respectively cut the corresponding press cutting layer 11 and then break up the fracturing layer 12, allowing that the jigsaw puzzle blocks 10 be separated from each other. Because the fracturing location is in the middle of the jigsaw puzzle block 10 thicknesswise, it may avoid resulting in injury and is safe in use. During fabrication, it is enough to cut the press cutting layer 11 using tool 2. The fracturing layer 12 may be broken up by the consumer during use.

Preferably, the press cutting layer 11 is of wooden board layer and the fracturing layer 12 being of cardboard layer. Relatively, the cardboard layer is more easily to be fractured such that the jigsaw puzzle board 1 is more easily divided into a plurality of jigsaw puzzle blocks 10 after press cutting and, also, the paper quality at fracturing location will not result in injury. Preferably, both surfaces of the jigsaw puzzle blocks 10 are printed with patterns and words. The patterns or words on the surfaces of at least two jigsaw puzzle blocks 10 can correspond to each other, constituting continuous patterns or words. Besides, the cardboard layer is relatively more easily fractured than the wooden board layer. Therefore, during press cutting, the cardboard layer will not cause debris like those resulted in wooden board layer at the time of separation during press cutting. There is a possibility that the wooden debris may be attached on the cutting edges of the wooden board, causing inconvenience and danger to the users. Preferably, the fracturing layer 12 is in the middle of the jigsaw puzzle blocks. The first press cutting layer assembly located above the fracturing layer and the second press cutting layer assembly below the fracturing layer may also cover at least one press cutting layer. The said at least one press cutting layer is made of wood or plastic, i.e. wooden board layer. The said wooden board layer may be plywood. Alternatively, the press cutting layer may be made of plastic. The fracturing layer is made of paper, i.e. cardboard layer. The said cardboard layer may have a thickness between 0.2 mm and 1 mm. Of course, the fracturing layer 12 may be of the other materials which are easily fractured. For the purpose of convenient package and allowing that the users to understand the patterns on both sides of the jigsaw puzzle before using this creation, there shall be at least two jigsaw puzzle blocks of which partial fracturing layers may be connected each other such that users only need to break up the partial paper-made fracturing layer, afterwards dividing the jigsaw puzzle into a plurality of jigsaw puzzle blocks The connecting part of the aforesaid fracturing layer has a thickness between 0.02 mm and 0.2 mm. Alternatively, the press cutting layer 11 may be of plastic and the other material qualities. Preferable, the first press cutting layer assembly has a thickness roughly equal to that of the said second press cutting layer assembly. Furthermore, the grain patterns of two wooden board layers within the first or second press cutting layer assembly are alternatively arranged. With grain patterns in relatively different directions, two wooden board layers was combined as the first or second press cutting layer assembly to enhance the structural strength of the jigsaw puzzle blocks 10. Moreover, the first or second press cutting layer assembly may only be comprised of one wooden board layer. Preferably, one wooden board layer of the first press cutting layer assembly and that of the second press cutting layer assembly is set up with grain pattern in relatively different directions to enhance the structural strength of the jigsaw puzzle blocks 10. Furthermore, two surfaces of the jigsaw puzzle blocks are disposed of patterns. The surface patterns of at least two jigsaw puzzle blocks can correspond to each other, constituting continuous patterns. The lateral edges of the jigsaw puzzle blocks 10 are arc surfaces. The arc angular diameter of the lateral edge R is preferably between 1 mm and 3 mm (see FIG. 3). That the lateral edges of the jigsaw puzzle blocks 10 are arc surfaces such that the people can hardly identify the front and opposite sides. With coordination of different printed patterns, the jigsaw puzzle blocks may be more challenging, making it more pleasurable to play with.

The embodiments of this invention and creation are described as above with accompany drawings. However, the invention and creation is not limited to the aforesaid embodiments. They are only exemplary instead of limitation. It will be appreciated that those skilled in the art, upon attaining an understanding of the foregoing, may readily conceive of alterations to, variations of and equivalents to these embodiments without departing from the spirit and scope of the disclosure, which all fall into the scope of protection for the present invention and creation.
